ALPAGE webmapping platform

The research programme ALPAGE has created an online webmapping platform incorporating maps and spatial data of historic Paris for public use. This platform, makes it possible to carry out mapping online: it is therefore possible to produce a map of Paris from data available in the ALPAGE GIS. This data, which is made up of either raster (plans) or vector (points, lines, and polygons) data, concerns mainly the pre-industrial period (medieval and modern eras).

The webmapping platform (French version only) is currently delivered using the Dynmap software (version 7) published by the French company Business Geografic and for which the TGIR Huma-Num has acquired a proprietary licence. The interface is mainly made up of a georeferenced map window on which the user can superimpose any available data layer listed in the layer table (using the tab “affichage” to the left of the map). Although the interface provides tools that are similar to other desktop GIS software, users are advised to consult the user guide in order to benefit fully from the platform functionalities. Furthermore, 'Menestrel' the medieval history web portal provides information on the use of GIS in historical and archaeological contexts.

A first approach would be a relatively simple use of the platform involving the use of the tabs “Standard” and “Avancé” that are displayed by default: in this way any user can navigate around the Parisian area, display and view data at will, and lastly export a map which will automatically show north, contain a legend, include the image copyright as well as the symbology of the map defined by the ALPAGE team.

A second approach involves a more expert use of the platform allowing users to make their own thematic analyses by filtering data and by modifying at leisure the symbology of a vector data layer. To do this, bring up the tab “Perso” by clicking on “Connexion” (at the bottom of the layer table) and fill in the requested codes that we have simply defined as “publique”; “publique”.

A third and final possible use of the platform is aimed at anyone who wishes to manage in an optimal way the data processes. In order to do this the user needs to request the creation of a private account, involving personal codes (not the case in the aforementioned approach). Contact us to set up this option.
